I need a reliable way to reach a second Android phone that stays in another city so the service app running on it can keep using its own GPS while I supervise the device. Through Wi-Fi, I must be able to: • see and fully control its screen in real time • copy, delete, or push files both ways without having someone touch the phone Your task is to choose or build the simplest, most secure solution—whether that means configuring TeamViewer Host, AnyDesk, AirDroid, an ADB-based approach like scrcpy/VNC, or another method you know will hold a stable unattended session over Wi-Fi. Please handle everything from initial setup steps I’ll follow on each handset, through permissions and battery-optimised settings, to a short hand-off guide so I can reconnect whenever I need....

I’m collaborating with top AI research labs and need seasoned engineers who can pick up well-scoped tasks from our backlog, implement them to a high standard, and submit merge-ready code.

I need a programmer to fix a UTC (time zone) bug in an open-source astrology program that casts birth charts. The issue occurs when entering birth data for individuals born in India, where the program incorrectly lists UTC as xx:21. UTC should only ever be listed as xx:00, xx:30, or xx:15 (for Nepal). The task involves identifying and correcting this bug. Familiarity with astrology jargon is preferred but not required. I can provide specific birth data for testing and verification purposes. Other locations like Germany, USA, and UK have been verified as accurate.

I need someone to use writing skills to answer a series of questions

I want a complete Roblox simulator focused entirely on eggs. Players should roam the map collecting eggs, then hatch them to reveal pets, boosts, or surprises. Each time an egg is hatched the player gains +1 Bat Power—this single stat will drive progression, unlock zones, and gate special rewards, so please wire it cleanly into leader-stats and data-store saving. My vision is light-hearted and colorful, not tied to any existing IP, just an original “egg world” that feels fun the moment you join. Think wide open areas with scattered egg spawns, a visible hatchery zone, and clear UI feedback whenever Bat Power increases. Core features I need delivered: • Egg spawning, pickup, and inventory handling • Hatch animation and reward logic • Persistent +1 Ba...

I’m developing a next-generation Bitcoin miner, internally labelled “400,000,” and I need an engineer or small team to drive the research-and-development phase. My priorities are clear: push Energy efficiency as far as current silicon will allow, unlock higher Processing power than today’s leading rigs, and experiment with new or optimised Mining algorithms. I also want the design to remain flexible enough to switch over to Bitcoin Cash should comparative profitability shift. At this stage the unit’s final home is undecided—my form literally says “Dinner,” which simply means I’ll be bench-testing the prototype in an ordinary room rather than a purpose-built data centre. Noise, thermal load and power draw therefore have to stay within l...

I have a Cognex vision camera already mounted above a high-speed food-and-beverage packaging line. Its only job is quality inspection, specifically spotting packaging defects such as poor seals, tears, or misapplied film before the product leaves the line. What I need now is a seasoned Cognex programmer who can log in remotely, create the vision job, and stay on call while we validate it on live production. The hardware is in place and networked; I can provide a stream of sample images, live video, and remote desktop access to In-Sight Explorer. The project involves choosing the right tool chain (Edge, Histogram, Blob, PatMax—whatever delivers reliable results), setting proper exposure and calibration, then mapping the pass/fail result to our PLC over Ethernet/IP so the reject gate ...

I want to bring a Five-Nights-at-Freddy’s atmosphere to Roblox while keeping the core gameplay firmly incremental. Players will start small and, through steady progression, unlock systems, rooms, and mechanics until they are running a fully functioning facility—all inside a tense, animatronic-haunted setting. The project’s main goal is simple: deliver a full, working game that feels just as satisfying to grow as it is unsettling to survive. Gameplay type: incremental Primary focus: building the entire experience from the ground up rather than just a single mechanic Mode: multiplayer—data must replicate correctly across servers, and progress must save between sessions. You’ll work in Roblox Studio with Lua, creating everything from resource generators and...
